The investigational part of this study is using a mobile PET/CT scanner to take images of the participants tumor immediately after they are treated with proton radiation. This allows the participant to be treated and imaged on the same bed. The information obtained may improve the accuracy of treatment and may help to minimize the dose delivered unnecessarily to healthy tissue.

Primary Outcome Measures:
  • Effectiveness [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Acquire PET/CT scan data in list-mode on patients undergoing external beam proton radiotherapy for brain and soft tissue tumors in head. Analyze these data to assess the effectiveness of using PET/CT for in-room PET monitoring for proton radiation therapy quality assurance.

Secondary Outcome Measures:
  • Optimize the in-room PET acquisition length [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Reconstruct these list-mode PET data for different scan durations and optimize in-room PET acquisition length

Estimated Enrollment: 39
Study Start Date: October 2010
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Participants 1-39
PET Scan done right after one radiation treatment is complete and will take 15-20 minutes. After undergoing their first PET scan, participants will have the option to undergo 1-2 additional scans throughout radiation treatment in the same manner as the first scan.
Procedure: PET scan
In-Room PET scan

Detailed Description:

For all participants, right after one regular treatment fraction, NeuroPET or NeuroPET II will be wheeled into the patient room. The patient bed will be moved directly into the scan position and a PET scan will be acquired in list-mode for 15 to 20 minutes followed by a CT scan for ~5 minutes. After undergoing their first PET scan, participants will have the option to undergo 1-2 additional scans throughout radiation treatment in the same manner as the first scan.
